Maybe you forgot to compile the generation binary for arm64?

Turbo boost is working fine here on Link w/ coreboot 4.20 and Win10 22H2

See: https://github.com/coolstar/edk2/tree/upp_202301_secureboot_pxe for working Secure Boot and PXE

Headphone issue is an issue with kernel not sending EAPD HDA verb (to node 0x10) after loading codec firmware

Flashed 4.20.1 + booted Windows 10 20H2 here on Link w/ Creative SoundBlaster Recon3Di driver. Can confirm speakers and headphone jack both functional

Suspend/Resume works fine on Link here on both Manjaro and Win10 22H2

Not a coreboot issue. Key mappings are controlled by Wilco EC which is closed source

no, I'm talking about get_reliable_rw(). Adding the `__attribute__ ((optnone))` macro to it works around the issue in Release builds (but of course it disables compiler optimizations in that function)

oops yeah I said the part it fails at wrong. It actually fails at "Overwriting shmem size to have safe OOB"

Can confirm random kernel panics here... seems to happen about 4-5 days of uptime, even without Mobile Substrate or any tweaks running
